Ninety-five percent of e-mails sent in 2007 are junk

Barracuda Networks released its annual spam report, which shows between 90 to 95 percent of all e-mail sent in 2007 is spam.
Barracuda Networks released its annual spam report, which shows between 90 to 95 percent of all e-mail sent in 2007 is spam. This is based on an analysis of more than 1 billion daily e-mail messages sent to its more than 50,000 customers worldwide.

The above figures represent an increase from the estimated 85 to 90 percent of all e-mails being spam in 2006.

It appears that the CAN-SPAM Act was, as expected by many, useless in curbing spam. According to the report:

This growing proportion is even more significant when compared to 2004, when the federal CAN-SPAM Act, which set parameters for sending unsolicited email and defined penalties for spammers, went into effect. At that time spam was 70 percent of all email. In 2001, spam accounted for only five percent of email messages.

Interestingly, Barracuda Networks' poll, as dissected by CNET's Matt Asay, shows that 50 percent of users received five or fewer spam e-mails in their inbox per day. About 65 percent received less than 10 spam messages each day, while 13 percent were inundated with 50 or more spam e-mails daily.

In addition, spam techniques have changed over the years:

  • 2007 - Obfuscation techniques and increased usage of attachments, such as PDF spam
  • 2006 - Image spam, botnets
  • 2005 - Rotating URL spam
  • 2004 - Automated generation of spam variants
  • 2003 - Open relays, blast emails, spoofing

I wonder what kind of spam the year 2008 will bring. What are your thoughts on this matter?

It's long past time for free email. All email should require prepaid postage/fees.

I think it's going to move to the cellular networks where there is currently no method of filtering available and everyone's email address is phonenumber@mobile.carrier.com. It's so easy I don't know why it hasn't happened yet.

The techniques derived by spammers change with time as they get more advanced, the nature / contents of the spam emails are ever more annoying, email users increase by the day though thier understanding of what to view and what not to bother with gets better with time, but this increase provides for more and more destinations for all sorts of spam... sad.

My prediction is: Every single banking, investment, shopping and premium service website is going to be targeted by phishing and spoof attempts, several times a day, every day. And I believe that some responsibility lies with the domain registration authorities that allow names like paypai.com, e8ay.co.uk, goggle.com etc.. to be registered when they can only be used for one thing: spoofing.
